DESCRIPTION

dpns_setfsize
sets the filesize for a regular file; set also the last modification time to the
current time.
This function should only be called by the stager after the last write
operation has been performed on the file.
The file can be identified by
path
name or by
file_uniqueid.
If both are specified,
file_uniqueid
is used.

path

specifies the logical pathname relative to the current DPNS directory or
the full DPNS pathname.

csumtype

specifies the type of checksum. Valid types are:

CS

standard 32 bits checksum

AD

Adler 32 bits checksum

MD

MD5 128 bits checksum

RETURN VALUE

This routine returns 0 if the operation was successful or -1 if the operation
failed. In the latter case,
serrno
is set appropriately.

ERRORS

ENOENT

A component of
path
prefix does not exist or
path
is a null pathname.

EACCES

Search permission is denied on a component of the
path
prefix or the caller effective user ID does not match the owner ID of the file
or write permission on the file itself is denied.

EFAULT

path
and
file_uniqueid
are NULL pointers.

ENOTDIR

A component of
path
prefix is not a directory.

EISDIR

The file is not a regular file.

EINVAL

The length of the
csumtype
exceeds 2 or
csumtype
is an unknown type or the length of the
csumvalue
exceeds 32.

ENAMETOOLONG

The length of
path
exceeds
CA_MAXPATHLEN
or the length of a
path
component exceeds
CA_MAXNAMELEN.
